EUGENE FULLER, OF PROVIDENCE, RHODE ISLAND.

LACING-TIP.

Specification of Letters Patent.

Application filed October 20, 1919. Serial No. 331,972.

lacin fabric so that it cannot be removed therefrom, and also to provide a tip which is handsome and attractive in appearance.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings:

Figure 1-is an enlarged side elevation showing right and left hand helically-disposed grooves formed in the surface of a tip.

Fig. 2is a view illustrating my improved method of applying a tip metal of double width to the lacing and providing an annular groove therein where the tip is subsequently severed leaving beveled edges at the end of each tip.

3-is a longitudinal section of the tip with the lacing removed; showing the inwardly projecting ribs which form diamond-shaped recesses into which the fabric of the tip is forced and retained.

l is a section on line 4-4; of Fig. 3 illustrating another view of the pockets into which the lacing-fabric is forced when the metal is pressed about the same.

Referring to the drawings, 10 designates the body of the tip, which is preferably formed of sheet metal and of a width double the length of a finished tip.

This tip metal is applied to a folded portion of the lacing 11 and bent around the same under pressure, by means of dies (not shown).

These dies are so shaped that when they are brought together about the lacing tip, they may be caused to swage right and left hand helically disposed grooves 12 and 13 in the outer surface of the metal body thereby forming correspondingly inwardly extending ribs 14 and 15, which angularly disposed ribs are forced into the fabric to bite and retainthe same. These ribs are shown as forming between them diamond-shaped recesses 16 into which the lacing fabric is forced, thereby providing most effective means for securely gripping the fabric of the lacing and preventing the tip from being withdrawn therefrom under the most severe conditions.

Another advantage of my improved construction of tip which is provided with both right and left hand helical grooves, is that asthese grooves are set on an angle the tip will pass much more smoothly through an eyelet than would be possible with the beaded. style of tip which is provided with annular grooves.

Then again by forming right and left hand helical grooves in a tip no turning of the tip on the fabric in either direction would have a tendency to unscrew the tip from the fabric and further by the use of both right and left hand-'helically disposed grooves the pockets or recesses 16 which are formed on the inner side of the tip will serve to effectually prevent rotation of the tip upon its fabric, which is not the case with a beaded tip having annular ribs formed about it.

hen forming a tip metal of a double length and applying the same to a lacing I so shape the dies that they will form an annular substantially V shaped recess 17 about midway between the edges thereof, and then upon severing the tip metal through this annular groove I leave the ends of each tip tapered as at 18 which serves both as a finish to the end of the tip and also assists in its ready entrance into an eyelet.

My improved tip is simple and inexpen sive to construct, positively secured to the lacing-fabric without any possibility of being accidentally removed therefrom, is very handsome and attractive in appearance and is inexpensive to apply to the lacingfabric.

I do not wish to be restricted to forming the inner retaining recesses in diamond shape, as they may be formed in any shape.

The foregoing description is directed solely toward the construction illustrated, but I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claim.

I claim. A lacing tip having a body of sheet ma- 5, terizil applied to the compressed fabric of the lacing in tubular form, said body being provided with opposite diagonally-disposed intersecting angular grooves in its outer surface forming correspondingly imvurdlyextending ribs providing dinmend-shaped 10 recesses between said intersecting grooves in which recesses the lacing fabric is retained.

In testimony whereof I afiix my signature.
